NJM2845DL1-33-TE1

Nisshinbo Micro Devices Inc. · Linear Voltage Regulators (LDO) · TO-252

NJM2845DL1-33-TE1 from Nisshinbo Micro Devices Inc., in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Supply input pin; absolute maximum +14V, operating range up to Vo+9V, with a 0.33µF or greater input capacitor placed close between VIN and GND.
2 GND power_in Ground pin for the regulator.
3 VOUT power_out Regulated 3.3V output (-33 version) with Io(max) 800mA, requiring a 2.2µF ceramic output capacitor connected to GND.
